comment What happened when i “mv *” no errors shown and now only one folder left. Why?
@Jarmund I think it's safe to assume some *nix, considering that both commands mentioned are common commands on Unix-like systems. In this regard, I think it's safe to say that most shells work the same. So we can deduce enough to give a useful answer even though the exact platform is not explicitly stated.

This. By the way, if you want to use * in a mv (or cp) then have a look at their --target-directory switch. It ensures that you don't get bit by things like this.

comment Domain [ Understanding ] issue when creating a Linux email server
Honestly (and really, no offense intended), if you don't know what you are doing then you shouldn't be running your own VPS but rather just stick with paying someone else to do the hard stuff; it'll be easier for you and likely less frustration for others. Even more so if you are providing something for others. Use your favorite search engine to look up virtual hosting, but don't forget that "making it work" is only a small part of running an Internet-exposed server. Keeping it secure and properly locked down is not a task to be taken lightly either.

comment Why doesn't TrueCrypt support system encryption on non-Windows machines?
"if one separates system from data partitions, the former don't usually contain interesting data one might want to access from another OS" Well, not really true. If the kernel, other boot files and system binaries are unprotected, it's trivial to plant malicious code into the system partition. You could, for example, extract the kernel build configuration, make a new kernel of the same version and with the same configuration but which stores to some unencrypted location all keyboard I/O while cryptsetup is running, and have a trivial way of entry into the supposedly protected data.

Look up "virtual hosting" in the context of email.

comment Why do English characters require fewer bytes to represent than other alphabets?
I don't think UTF-8 was so much designed for efficiency with ASCII data as for compatibility. UTF-8 has the very nice property that 7-bit ASCII content (with the high bit set to zero) is identical to the same content encoded as UTF-8, so for tools that normally deal with ASCII, it's a drop-in replacement. No other Unicode encoding scheme has that property, to my knowledge. UTF-8 is also reasonably compact for most data, particularly if you stay within the realm of the Unicode BMP.

comment How to use the Internet while Heartbleed is being fixed?
"Until and unless there is evidence that this vulnerability was exploited" "If there is evidence of exploitation, we must react to that appropriately." You talk a lot about evidence of exploitation. Yet one of the scary things about the Heartbleed bug is that successful exploitation is undetectable after the fact (unless you're storing the incoming heartbeat message in full every time in perpetuity, and even then it's not guaranteed that successful exploitation led to a breach of security). How do you propose we establish after the fact evidence of successful exploitation of the bug?

comment Understanding Windows Routing Tables and Default Gateways
Considering which versions of Windows you're talking about and the general tone of this post, I'm guessing you are in a corporate environment, in which case you may want to consider flagging this post for moderator attention and requesting migration to Server Fault.

comment Understanding Windows Routing Tables and Default Gateways
If you want to stop RFC 1918 space packets from going out, just null route 10/8, 172.16/12 and 192.168/16 (or route them back to your LAN). Absent special arrangements those packets shouldn't enter/exit your network anyway. Though I'm not at all sure that's the best approach (it might break things at some other end).

comment How to boot from new hard drive
Note that jumper positions vary between drives. It's usually printed on the drive's identifying label which jumper positions correspond to which features, including master/slave/cable select, delayed spinup, etc. Make very certain to double-check the jumper positions before you apply power.

You could perhaps build a Lego robot that unplugs and replugs the power and phone wiring going to the cable modem at appropriate intervals?
